Abstract
This study was conducted to investigate the effect of aging treatment from 300 °C to 420 °C on the mechanical properties of the pressure tube material at 310 °C, which is outlet temperature pressure tube in CANDU reactor. The short range ordering (SRO) phenomenon during aging process is confirmed by..... More

Abstract
Austenitic stainless steels are widely used in a variety of industries, such as power plants, aerospace, automotive, construction and electronics, due to their excellent mechanical properties including ductility, toughness and corrosion resistance. For application in various industries, many parts and products require plastic processes such as cold rolling, cold forging..... More

Abstract
This study investigated the effect of Si on the characteristics of FCA multi-layer weld metal with 460 MPa yield strength grade steels for ships and marine structures. The effect on microstructure was evaluated by tensile, charpy impact and CTOD testing of 4 FCAW welds containing various C and Si contents...... More

Abstract
Graphite fiber attracted much attention in the area of aluminum based composite due to its low density and high strength. However, one of the major drawbacks in fabricating graphite reinforced metal matrix composites (MMCs) is that aluminum generally does not wet graphite. Therefore, it is difficult to impregnate the graphite..... More

Abstract
The leaching behavior of silver from electronic scrap using acidic thiourea solution was studied. The results showed that the silver leaching percentage was affected by the concentration of thiourea and hydrochloric acid, the oxidant such as ferric ions, solid-liquid ratio, temperature, rpm, etc. The leaching percentage of silver decreased with.....

Abstract
This study investigated the crystal structure and mechanical properties of copper foil electroplated by adjusting gelatin and chloride ions from 0 to 100 ppm. There was increased formation of spherical crystals and surface roughness on the surface of the electroplated layer when the gelatin was added, and the direction of..... More

Abstract
To improve the hydrogen uptake and release properties of magnesium (Mg), five weight percent of graphene was added to pre-milled Mg by milling in hydrogen (reaction-involving milling). The hydrogen uptake and release properties of the graphene-added Mg (named Mg-5graphene) were investigated. Premilling of Mg (for 24 h) and then adding..... More

Abstract
Cu₂Se exhibits very low thermal conductivity and the origin is known to be the "liquid-like" behavior of Cu ions around the sub-lattice of Se. Due to its very high ZT, research interest in the thermoelectric properties of this material has been increasing rapidly. However, most studies have used a conventional melting..... More

Abstract
We report the effect of interface control using multiwalled carbon nanotubes (MWCNT) on thermoelectric properties of TiO₂. By consolidating TiO₂ nanoparticles with MWCNT (0.5, 1, 2, 4, and 8 wt%) using spark plasma sintering, we prepared interface-controlled TiO₂-MWCNT nanocomposites, where TiO₂ grains were surrounded with a MWCNT network. Simultaneous control of..... More

Abstract
Iodine-doped n-type Bi_2-xSb_xTe_3-ySe_y:I_m (x = 0.1–0.2, y = 0.15–0.6, and m = 0.0025–0.005) quaternary solid solutions were prepared by encapsulated melting (EM) and hot pressing (HP). The lattice constants of the resulting materials decreased with increasing Sb and Se contents, whereas the amount of I dopant was too small to..... More
